Here is the White House announcement, reproduced below…(the deployment to Europe appears to be potential rather than immediate):
Before reading it, see this quote from the website stripes.com:
“Since 2014, U.S. European Command has provided combat-credible forces for rotational deployment to Europe … to demonstrate good commitment to NATO,” Army Lt. Gen. Douglas Sims, director of operations for the Joint Staff, told reporters Thursday. “This reaffirms the unwavering support and commitment to the defense of NATO’s eastern flank in wake of Russia’s illegal, unprovoked war on Ukraine.”
“By the authority vested in me as President by the Constitution and the laws of the United States of America, including sections 121 and 12304 of title 10, United States Code, I hereby determine that it is necessary to augment the active Armed Forces of the United States for the effective conduct of Operation Atlantic Resolve in and around the United States European Command’s area of responsibility.
“In furtherance of this operation, under the stated authority, I hereby authorize the Secretary of Defense, and the Secretary of Homeland Security with respect to the Coast Guard when it is not operating as a service in the Navy, under their respective jurisdictions, to order to active duty any units, and any individual members not assigned to a unit organized to serve as a unit of the Selected Reserve, or any member in the Individual Ready Reserve mobilization category and designated as essential under regulations prescribed by the Secretary concerned, not to exceed 3,000 total members at any one time, of whom not more than 450 may be members of the Individual Ready Reserve, as they deem necessary, and to terminate the service of those units and members ordered to active duty.
“This order is not intended to, and does not, create any right or benefit, substantive or procedural, enforceable at law or in equity by any party against the United States, its departments, agencies, or entities, its officers, employees, or agents, or any other person.”
JOSEPH R. BIDEN JR.

BBC does not mention it: this snip is from noon London time in the BBC News’s “War in Ukraine” section (I also did a search):
